Material properties and testing

The engineering properties of foundation and dump materials are required for design of dump slopes. Selecting and obtaining representative samples for materials testing, interpreting results and applying them to design requires a thorough understanding of the various components of the physical environment. The type and amount of testing required varies, depending on the complexity of site conditions, the location, type, size and configuration of dump, the environmental sensitivity of the site, etc. For large dumps, or dumps located on a complex and environmentally sensitive site, substantial detailed testing may be required. In cases where a probabilistic approach to design is adopted, a large testing program may be required to supply sufficient data for statistical analysis.
